[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The height-adjustable display stand of the utility model comprises a base 2, a support rod 4 and a cross bar 12. A support rod 1 is fixedly arranged on the upper end of the base 2, a toggle block 3 is rotatably arranged on the support rod 1, an empty slot 5 is arranged inside the support rod 1, a screw 6 penetrating the empty slot 5 is arranged on the upper end of the toggle block 3, the support rod 4 is inserted into the empty slot 5, and the screw 6 can be inserted into the support rod 4, the screw 6 is threadedly connected with the support rod 4, the cross bar 12 can be adjusted in angle at the top end of the support rod 4, and a positioning plate is arranged at the front end of the cross bar 12;

[0025] In this structure, the crossbar 12 can be supported by the support rod 1 and the support rod 4, and the display can be fixed on the positioning plate;

[0026] When it is necessary to temporarily adjust the height of the display, rotating the toggle block 3 can rotate the screw rod 6. At this time, through the principle of the threaded structure, the support rod 4 can be extended or retracted in the empty slot 5, and then the cross bar 12 can drive the display to adjust the height. This structure adopts a purely manual adjustment method, which is not only simple to operate, but also does not rely on an external power supply, and has few limitations during use.

[0027] In this structure, a driven block 11 is fixedly arranged at the rear end of the cross bar 12, a rotating shaft 7 is arranged at the top of the support rod 4, a limiting plate 8 is fixedly arranged at the lower end of the rotating shaft 7, a driving block 9 is fixedly arranged at the lower end of the limiting plate 8, a positioning shaft 10 is arranged at the lower end of the driving block 9, and a positioning shaft 10 is rotatably connected to the top of the support rod 4 is arranged at the lower end of the driving block 9, the driving block 9 is meshed with the driven block 11, a positioning rod 13 is fixedly arranged at the top of the support rod 4, the driven block 11 is fixed at the top of the positioning rod 13, and the driven block 11 can rotate at the top of the positioning rod 13, a plurality of limiting rods 14 are arranged at the top of the support rod 4, and a limiting plate 8 is provided The limiting rod 14 passes through the limiting hole 15. In this structure, the driving block 9 and the driven block 11 are fully engaged, so the driven block 11 will not swing on one side of the driving block 9. The number of limiting holes 15 is not specified. When it is necessary to temporarily adjust the angle of the display, the limiting rod 14 is pulled out, and then the rotating shaft 7 is rotated, so that the driving block 9 can drive the driven block 11 to rotate through the engagement, and then the cross bar 12 can drive the display to rotate a certain angle. When the angle of the display is adjusted, take the limiting rod 14 and insert the limiting rod 14 into the specified limiting hole 15, so that the angle of the display can be easily adjusted.

[0028] Furthermore, the outer wall of the toggle block 3 is provided with anti-slip grooves, which can make the outer wall of the toggle block 3 rougher and facilitate the rotation of the toggle block 3.

[0029] If the support rod 4 is circular, when the screw rod 6 rotates, it is easy to cause the support rod 4 to rotate together. The empty groove 5 and the empty groove 5 can be rectangular. When rotating, the support rod 4 will not rotate together, which can make the support rod 4 more stable when lifting.

[0030] In this structure, the bottom end of the positioning rod 13 is fixed to one side of the support rod 4 by screws, and the support rod 1 is fixed to the upper end of the base 2 by screws. The screw fixing method has the advantage of convenient assembly, which can facilitate the assembly of the positioning rod 13 and the support rod 1.
